INVENTOR ATTORNEY-5 Patented June 10, 1930 UNITED STATES GUY W. SMITH, OF KALAMAZOO TOWNS ROSIN-RECLAIM Application led March 16,

The main objects of this invention are:

First, to provide a rosin reclaiming machine for recovering rosin from the emptied container that is very simple in construction and effective in operation.

Second, to provide a means for collecting the rosin after removing the same from the barrel staves.

Third, to provide a means whereby the staves of emptied rosin barrels can be driven at a speed to be thoroughly cleaned.

Objects pertaining to details and economies of construction and operation will definitely appear from the description to follow. The invention is defined in the claims.

A `device embodying my invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 isr a perspective view of my improved reclaiming machine, parts being broken away for clearness and convenience in illustration, only a portion of the collecting boX and receptacle being shown.

Fig. 2 is a vertical section on line 2 2 of Fig. 3, a stave inserted in the machine indicating the process of beating and the machine being at a standstill.

Fig. 3 is a partial longitudinal section online 3-3 of Fig. 2, partsbeing shown in full lines.

The parts of the drawing will be referred to by their numerals of reference which are the saine in all the views.

1 is the frame of my improved rosin reclaiming machine. 2 are the supporting legs therefor. 210 are the cross members. 8 are intermediate cross supporting members. 4 is the drive shaft, 4:1 is the drive pulley and 42 are the journal supports. 5 is my improved beater drum secured to the drive shaft by any suitable means. 51 are pivotally mounted beaters of a single link construction and 52 are slots in the drum.

`are connecting links inserted therethrough for pivotally mounting` the beaters. 54C are locking links inside the drum.

6 is the table support for the work consisting of parts 61 and the slightly inclined part G2. A way 63 is formed between the two inner ends of the parts 61 and 62. 61

parts thus arranged a very reclaiming machine has been produced. The staves of emptied i'osin barrels as they come from the consumer of rosin are coated With a co nsiderable amount of rosin which, of course, is waste, and this machine reclaims the saine by beating and collecting, although my machine does not remove all the rosin. tially impregnated in A small amount is parthe wood and can not be separated by beating.

ted two at a time, this easily handled by a man After the staves are the action of the beatto drive them through To facilitate the driving, the provided to frictionally enstaves and carry them 104 is a downy' flange on the end of the table,

As the staves are passed through they are brushed by the flexible strips which help to retain the rosin dust in the suction chamber by causing a restricted inflow of air against the staves. The rosin dust and chips rare taken through the fan and discharged into the dust chamber. The chamber in this iembodiment is a square frame 112 covered by any suitable porous fabric that allows the air to effectively pass therethrough. 'The collected rosin may be passed through a general process of refining. The beaters 51 are of the single link type supported by a'link 53 through the slots 52 in the drum.

The beaters are set ina staggered relation to beat the entire width of the stave as it passes through the machine. Although a plurality of links can be used with the same results, the only objection to using the plurality is that there are too many wearing surfaces to make this practical. A bar of metal perforated at one end and pivotally mounted on the link 58 would also do the work with the desired effect.

Having thus described my invention what I claim as new and desire to secure by Letters atent is:

l. A machine for recovering rosin from used barrel staves comprising a suitable table, a suction housing above the said table with .curtained apertures at front and rear for the passageof staves, a beater drum disposed in the lsaid housing with single link beaters pivotally connected to the exterior of said drum and adapted to swing downwardly to beat the rosin coated surfaces of a barrel stave passing therethrough, a feed roll comprising a shaft disposed in a recess in the top of a table to slowly advance the staves fed therethrough, a friction drive therefor from the beater drum shaft, a suction fan, the intake of which is connected to the said suction chamber to induce a strong inward Ycurrent of air entering the said chamber t0 retain and withdraw the powdered rosin, and I a collector to which said fan delivers covered my hand.
